Vesicant treatment with phenyl-thiophene type vitamin d receptor modulators

ABSTRACT

The present invention relates to a method of treating or preventing damage to human skin cells by chemical vesicants by administering a non-secosteroidal, phenylthiophene compound with vitamin D receptor (VDR) modulating activity.

CROSS REFERENCE TO RELATED APPLICATIONS

This patent application claims the benefit of priority under Title 35 United States Code, section 119(e), of Provisional Patent Application No. 60/439,575 filed Jan. 10, 2003; the disclosure of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

Chemical vesicants are typlified by bis(2-chloroethyl) sulfide (Chemical Agent Symbol HD), Cl(CH₂)₂S(CH₂)₂Cl, a compound that forms blisters by either liquid or vapor contactwith the skin. Related sulfur analogues of Agent HD are 1,2-bis(2-chloroethylthio)ethane (Chemical Agent Symbol Q), Cl(CH₂)₂S(CH₂)₂S(CH₂)₂Cl; and bis(2-chloroethylthioethyl) ether, (Chemical Agent Symbol T) Cl(CH₂)₂S(CH₂)O(CH₂)₂S(CH₂)₂Cl. Nitrogen analogues of the sulfur mustard are also vesicants and have the general formula RN(CH₂CH₂Cl)₂. Exemplary nitrogen mustards are tris(2-chloroethyl) amine (Chemical Agent Symbol HN3), N(CH₂CH₂Cl)₃; N-methyl-2,2′-dichlorodiethylamine (Chemical Agent Symbol NH2); and 2,240 -dichlorotriethylamine, CH₃CH₂N(CH₂CH₂Cl)₂ (Chemical Agent Symbol NH1).

The activity 1α,25-dihydroxyvitamin D3 in various systems suggests a wide range of clinical applications. Recently, chemical modifications of 1α,25(OH)₂D₃ have yielded analogs with attenuated calcium mobilization effects (R. Bouillon et. al., Endocrine Rev. 1995, 16, 200-257). One such analog, Dovonex® pharmaceutical agent (product of Bristol-Meyers Squibb Co.), is currently used in Europe and the United States as a topical treatment for mild to moderate psoriasis (K. Kragballe et. al., Br. J. Dermatol. 1988, 119, 223-230).

Other Vitamin D₃ mimics have been described in the publication, Vitamin D Analogs: Mechanism of Action of Therapeutic Applications, by Nagpal, S.; Lu, J.; Boehm, M. F., Curr. Med. Chem. 2001, 8, 1661-1679.

Synthetic VDR ligands have been synthesized. For example, a class of bis-phenyl compounds stated to mimic 1α,25-dihydroxyvitamin D₃ is described in U.S. Pat. No. 6,218,430 and the article; “Novel nonsecosteroidal vitamin D mimics exert VDR-modulating activities with less calcium mobilization than 1α,25-Dihydroxyvitamin D₃” by Marcus F. Boehm, et. al., Chemistry & Biology 1999, Vol 6, No. 5, pgs. 265-275.

Synthetic VDR ligands having an aryl-thiophene nucleus are described in U.S. provisional patent application Ser. No. 60/384151, filed 29 May 2002. Although 1-α,25-Dihydroxyvitamin D₃ has been suggested for treatment of sulfur mustard vesicants, there remains a need for more effective agents for treatment and protection of skin cellsfrom the adverse effects of vesicants.

SUMMARY OF THE INVENTION

Treatment and prevention of human skin cell damage by Mustard is done by contacting the skin cells with a pharmaceutically effective amount a compound represented by formula (I)

wherein the variables R, R′, Q₁, Q₂, R_(P), R_(T), L_(T), L_(P), Z_(T), and Z_(P) are as hereinafter defined. The inventors have discovered that compounds described herein display the desirable cell differentiation and antiproliferative effects of 1,25(OH)₂D₃ with reduced calcium mobilization (calcemic) effects.

In another aspect, the compounds of Formula (I) are contacted with cutaneous lesions to ameriorate or eliminate the effects of vesicants, particularly Mustard.

In another aspect, the compounds of Formula (I) are applied to tissues to promote wound healing from trauma initiated by toxic chemicals such as Mustard.

In another aspect, all of the preceding treatments are accomplished with reduced hypercalciurea and hypercalcemia.

In another aspect, the compounds of Formula I are used for the manufacture of a medicament for preventing or alleviating the effect of Mustard.

Definitions IA: Rule of Polarity and Lipophilicity for Substituents Pendant on the Compounds used in the Method of the Invention

The substituents L_(P), L_(T), Z_(P), and Z_(T) pendant on the compounds used in the method of the invention are constrained both by (i) the identity of each substituent, and (ii) the polar or lipophilic nature of each substituent. The occurance of “polar” and “lipophilic” is to be done in accord with the following Rule: RULE: The combined groups in formula I, II, III, IV and V represented by

may all be lipophilic, or one may be lipophilic and the other one polar; but both combined groups may not be polar. If any part of a combined group is polar, then the “combined group” itself is deemed polar. For example, in the group

if the divalent linking group -(L_(P))- is the polar group, —C(O)—NH— and Z_(P) is the lipophilic group, —CH₂—CH₂-(t-butyl); then the combined group is defined as “polar.” Definitions IB: Definition of “Polar” and “Lipophilic”

The term “lipophilic group” refers to any linking group

or any of the Z substituents

that is hydrophobic, preferring or attracted to a hydrocarbon loving, non-aqueous environment. Lipophilic linking groups in the practice of the method of invention are

where m is 0, 1, or 2, and each R40 is independently hydrogen, —CH₃, —F, —CH₂F, —CHF₂, and —CF₃. All other exemplified linking groups are polar.

Generally all linking groups containing only hydrocarbon subunit groups or hydrocarbon subunit groups in combination with ether or thioether groups are lipophilic. Moreover, fluorinated derivatives of such groups are considered lipophilic.

Lipophilic Z_(T) or Z_(P) groups in the practice of the invention are partially exemplified by

-   -   —O—CH₂—C(O)—C₁-C₅alkyl,     -   —O—CH₂—CH(OH)—C₁-C₅alkyl,     -   —O—CH₂—C(CH₃)(OH)—C₁-C₅alkyl,     -   —O—CH₂—CH(OCH₃)—C₁-C₅alkyl,     -   —O—CH(CH₃)—C(O)—C₁-C₅alkyl     -   —O—CH(CH₃)—CH(OH)—C₁-C₅alkyl,     -   —O—CH₂—C(O)—C(CH₃)₂—C₁-C₅alky,l     -   —O—CH₂—CH(OH)—C(CH₃)₂—C₁-C₅alkyl,     -   —O—CH₂—C(O)—C₁-C₅alkyl,     -   —O—CH₂—CH(OH)—C₁-C₅alkyl,     -   —O—CH₂—CH(OCH₃)—C₁-C₅alkyl,     -   —CH₂—CH₂—C(O)—C₁-C₅alkyl,     -   —CH₂—CH₂—CH(OH)—C₁-C₅alkyl,     -   —CH₂—CH₂—CH(OCH₃)—C₁-C₅alkyl,     -   —CH₂—C(O)—C₁-C₅alkyl,     -   —CH₂—CH(OH)—C₁-C₅alkyl,     -   —CH₂—C(CH₃)(OH)—C₁-C₅alkyl,     -   —CH(CH₃)—C(O)—C₁-C₅alkyl,     -   —CH(CH₃)—CH(OH)—C₁-C₅alkyl,     -   —CH(CH₃)—C(CH₃)(OH)—C₁-C₅alkyl,     -   1-hydroxycyclopentenyl,     -   1-hydroxycyclohexenyl,     -   1-hydroxycycloheptenyl,     -   1-hydroxycyclooctenyl,     -   1-hydroxycyclopropyl,     -   1-hydroxycyclobutyl,     -   1-hydroxycyclopentyl,     -   1-hydroxycyclohexyl,     -   1-hydroxycycloheptyl, and     -   1-hydroxycyclooctyl.

Conversely, the term “polar group” refers to any linking group

that is not a lipophilic group. The term “polar group” also refers to any Z substituent

that is not a lipophilic group. The term, “polar” as used herein generally refers to chemical substituents that are hydrophilic, preferring or attracted to an aqueous environment. An example of a polar linking group is a linking group selected from the following:

where m is 0, 1, or 2 and R40 is as previously defined.

Particularly preferred chemical species used in the method of the invention are represented by structural formulae P101 to P106 and P200 to P206 a pharmaceutically acceptable salt solvate or prodrug derivative thereof:

Other preferred compounds for the treatment of vesicant damage are those defined by structural formulae P101 and P200 to P206, as follows:

The salts of the Active Ingredients are an additional aspect of the invention. The skilled artisan will also appreciate that the family of compounds include acidic and basic members and that the present invention includes pharmaceutically acceptable salts thereof.

In those instances where the compounds of the invention possess acidic or basic functional groups various salts may be formed which are more water soluble and physiologically suitable than the parent compound. Representative pharmaceutically acceptable salts, include but are not limited to, the alkali and alkaline earth salts such as lithium, sodium, potassium, ammonium, calcium, magnesium, aluminum, zinc, and the like. Sodium and potassium salts are particularly preferred. Salts are conveniently prepared from the free acid by treating the acid in solution with a base or by exposing the acid to an ion exchange resin. For example, a carboxylic acid substituent on the compound of Formula I may be selected as —CO₂H and salts may be formed by reaction with appropriate bases (e.g., NaOH, KOH) to yield the corresponding sodium and potassium salt.

Included within the definition of pharmaceutically acceptable salts are the relatively non-toxic, inorganic and organic base addition salts of compounds of the present invention, for example, ammonium, quaternary ammonium, and amine cations, derived from nitrogenous bases of sufficient basicity to form salts with the compounds of this invention (see, for example, S. M. Berge, et al., “Pharmaceutical Salts,” J. Phar. Sci., 66: 1-19 (1977)). Moreover, the basic group(s) of the compound of the invention may be reacted with suitable organic or inorganic acids to form salts such as acetate, benzenesulfonate, benzoate, bicarbonate, bisulfate, bitartrate, borate, bromide, camsylate, carbonate, chloride, choline, clavulanate, citrate, chloride, chloroprocaine, choline, diethanolamine, dihydrochloride, diphosphate, edetate, edisylate, estolate, esylate, ethylenediamine, fluoride, fumarate, gluceptate, gluconate, glutamate, glycolylarsanilate, hexylresorcinate, hydrabamine, bromide, chloride, hydrobromide, hydrochloride, hydroxynaphthoate, iodide, isothionate, lactate, lactobionate, laurate, malate, maleate, malseate, mandelate, meglumine, mesylate, mesviate, methylbromide, methylnitrate, methylsulfate, mucate, napsylate, nitrate, oleate, oxalate, palmitate, pamoate, pantothenate, phosphate, polygalacturonate, procane, salicylate, stearate, subacetate, succinate, sulfate, tannate, tartrate, teoclate, tosylate, trifluoroacetate, trifluoromethane sulfonate, and valerate.

Certain compounds used in the method of the invention may possess one or more chiral centers and may thus exist in optically active forms. Likewise, when the compounds contain an alkenyl or alkenylene group there exists the possibility of cis- and trans-isomeric forms of the compounds. The R- and S-isomers and mixtures thereof, including racemic mixtures as well as mixtures of cis- and trans-isomers, and all tautomers are contemplated by this invention. Additional asymmetric carbon atoms can be present in a substituent group such as an alkyl group. All such isomers as well as the mixtures thereof are intended to be included in the invention. If a particular stereoisomer is desired, it can be prepared by methods well known in the art by using stereospecific reactions with starting materials which contain the asymmetric centers and are already resolved or, alternatively by methods which lead to mixtures of the stereoisomers and subsequent resolution by known methods. For example, a chiral column may be used such as those sold by Daicel Chemical Industries identified by the trademarks: CHIRALPAK AD, CHIRALPAK AS, CHIRALPAK OD, CHIRALPAK OJ, CHIRALPAK OA, CHIRALPAK OB, CHIRALPAK OC, CHIRALPAK OF, CHIRALPAK OG, CHIRALPAK OK, and CHIRALPAK CA-1.

By another conventional method, a racemic mixture may be reacted with a single enantiomer of some other compound. This changes the racemic form into a mixture of diastereomers. These diastereomers, because they have different melting points, different boiling points, and different solubilities can be separated by conventional means, such as crystallization.

The method of the present invention is also embodied in mixtures of Active Ingredients.

Prodrugs are derivatives of the compounds used in the method of the invention which have chemically or metabolically cleavable groups and become by solvolysis or under physiological conditions the compounds of the invention which are pharmaceutically active in vivo. Derivatives of the compounds of this invention have activity in both their acid and base derivative forms, but the acid derivative form often offers advantages of solubility, tissue compatibility, or delayed release in a mammalian organism (see, Bundgard, H., Design of Prodrugs, pp. 7-9, 21-24, Elsevier, Amsterdam 1985). Prodrugs include acid derivatives well known to practitioners of the art, such as, for example, esters prepared by reaction of the parent acidic compound with a suitable alcohol, or amides prepared by reaction of the parent acid compound with a suitable amine. Simple aliphatic or aromatic esters derived from acidic groups pendent on the compounds of this invention are preferred prodrugs. In some cases it is desirable to prepare double ester type prodrugs such as (acyloxy) alkyl esters or ((alkoxycarbonyl)oxy)alkyl esters. Particularly preferred esters as prodrugs are methyl, ethyl, propyl, isopropyl, n-butyl, isobutyl, tert-butyl, morpholinoethyl, and N,N-diethylglycolamido.

Prodrugs may be prepared by methods as follows

Pharmaceutical Formulations Containing the Novel Compounds Used in the Method of the Invention:

Pharmaceutical formulations used in the method of the invention are prepared by combining a therapeutically effective amount of Active Ingredient together with a pharmaceutically acceptable carrier or diluent. The present pharmaceutical formulations are prepared by known procedures using well-known and readily available ingredients.

In making the compositions of the present invention, the Active Ingredient will usually be admixed with a carrier, or diluted by a carrier, or enclosed within a carrier which may be in the form of a capsule, sachet, paper or other container. When the carrier serves as a diluent, it may be a solid, semi-solid or liquid material which acts as a vehicle, or can be in the form of tablets, pills, powders, lozenges, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), or ointment, containing, for example, up to 10% by weight of the compound. The Active Ingredient is preferably formulated prior to administration.

The Active Ingredient may also be delivered by suitable formulations contained in a transderm patch. Alternatively, the Active Ingredient may be delived to a patient by sublingual administration.

For the pharmaceutical formulations any suitable carrier known in the art can be used. In such a formulation, the carrier may be a solid, liquid, or mixture of a solid and a liquid. Solid form formulations include powders, tablets and capsules. A solid carrier can be one or more substances which may also act as flavoring agents, lubricants, solubilisers, suspending agents, binders, tablet disintegrating agents and encapsulating material.

Tablets for oral administration may contain suitable excipients such as calcium carbonate, sodium carbonate, lactose, calcium phosphate, together with disintegrating agents, such as maize, starch, or alginic acid, and/or binding agents, for example, gelatin or acacia, and lubricating agents such as magnesium stearate, stearic acid, or talc.

In powders the carrier is a finely divided solid which is in admixture with finely divided Active ingredient. In tablets the Active Ingredient is mixed with a carrier having the necessary binding properties in suitable proportions and compacted in the shape and size desired. The powders and tablets preferably contain from about 1 to about 99 weight percent of Active Ingredient. Suitable solid carriers are magnesium carbonate, magnesium stearate, talc, sugar lactose, pectin, dextrin, starch, gelatin, tragacanth, methyl cellulose, sodium carboxymethyl cellulose, low melting waxes, and cocoa butter.

Sterile liquid form formulations include suspensions, emulsions, syrups and elixirs.

The Active Ingredient may be dissolved or suspended in a pharmaceutically acceptable carrier, such as sterile water, sterile organic solvent or a mixture of both. The Active Ingredient may often be dissolved in a suitable organic solvent, for instance aqueous propylene glycol. Other compositions can be made by dispersing the finely divided Active Ingredient in aqueous starch or sodium carboxymethyl cellulose solution or in a suitable oil.

Ointment Formulation for Prevention or Treatment Vesicant Damage:

Treatment of visicant damage may be accomplished with topical application, by a formulation in the form of a cream, oil, emulsion, paste or ointment containing a therapeutically effective amount of Active Ingredient. The formulation for topical treatment contains from 0.5 to 0.00005 weight percent, preferably from 0.05 to 0.0005 weight percent, and most preferably from 0.025 to 0.001 of Active Ingredient.

For example, two semisolid topical preparations useful as vehicles for VDR modulators in treatment and prevention of psoriasis are as follows:

Polyethylene Glycol Ointment USP (p. 2495)

Prepare Polyethylene Glycol Ointment as follows: Polyethylene Glycol 3350 400 g. Polyethylene Glycol 400 600 g. To make 1000 g. 

-   -   Heat the two ingredients on a water bath to 65 C. Allow to cool,         and stir until congealed. If a firmer preparation is desired,         replace up to 100 g of the polyethylene glycol 400 with an equal         amount of polyethylene glycol 3350.

Hydrophilic Ointment USP (p. 1216)

Prepare Hydrophilic Ointment as follows: Methylparaben 0.25 g.  Propylparaben 0.15 g.  Sodium Lauryl Sulfate  10 g. Propylene Glycol 120 g. Stearyl Alcohol 250 g. White Petrolatum 250 g. Purified Water 370 g. To make about 1000 g. 

The Stearyl Alcohol and White Petrolatum are melted on a steam bath, and warmed to about 75 C. The other ingredients, previously dissolved in the water are added, warmed to 75 C, and the mixture stirred until it congeals.

For each of the above formulations Active Ingredient is added during the heating step in an amount that is from 0.5 to 0.00005 weight percent, preferably from 0.05 to 0.0005 weight percent, and most preferably from 0.025 to 0.001 weight percent of the total ointment weight.

Assay Methods

Use of the Assay Methods:

The evaluation of the novel compounds for use in the method of treating or preventing visicant damage isdone using a plurality of test results. The use of multiple assays is necessary since the combined properties of (i) high activity for the vitamin D receptor, and (ii) prevention of hypercalcemia must be achieved to have utility for the methods of treating diseases, which are also, aspects of this invention. Some of the tests described below are believed related to other tests and measure related properties of compounds. Consequently, a compound may be considered to have utility in the practice of the invention if is meets most, if not all, of the acceptance criteria for the above described tests.

The evaluation of the novel compounds of the invention for psoriasis is done using the Keratinocyte Proliferation Assay in combination with other assays that measure inhibition of IL-2 production and stimulation of IL-10 production in peripheral blood mononuclear cells (PBMCs).

Brief Description, Utility and Acceptance Criteria for the Assay Methods:

1. The RXR—VDR Heterodimer Assay:

This assay provides the VDR activity of a test compound. It is desirable to have low EC50 values for a compound in this assay. The lower the EC50 value, the more active the compound will be as a VDR agonist. Desired assay results are EC50 values less than or equal to 600 nM. Preferred assay results are less than 250 nM, and most preferably less than 150 nM.

2. The Caco-2 Cell Co-Transfection Assay:

The Caco-2 cell assay is an indicator for the undesirable condition of hypercalcemia. This co-transfection assay is a surrogate assay for in vivo calcemic activity of VDR ligands. It is desirable to have high EC50 values for a test compound in this assay. The higher the EC50 values for a compound the less calcemic it will be in vivo. Desired assay results are EC50 greater than or equal to 300 nM. Preferred assay results are greater than 1000 nM.

3. The OCN (Osteocalcin) Promoter Assay

The OCN Promoter Assay is an indicator and marker for osteoporosis. Desired assay results are EC50 less than or equal to 325 nM. Preferred assay results are less than 50 nM.

4. The Mouse Hypercalcemia Assay

The Mouse Hypercalcemia Assay is a six day hypercalcemia test for toxicity and selectivity. Acceptable test results are levels greater than 300 μg/kg/day. Preferred assay results are levels greater than 1000 μg/kg/day.

5. The Keratinocyte Proliferation Assay

This Assay is indicative for the treatment of psoriasis. An acceptable test result is IC50 value of less than or equal to 300 nM. Preferred assay results are IC50 values of less than 100 nM.

6. The IL-10 Induction Assay

This is an in vitro efficacy assay for psoriasis, abscess and adhesion. Psoriasis involves both keratinocytes and immune cells. IL-10 is a unique cytokine because it is anti-inflammatory and immunosuppressive. This assay tells us whether a VDRM is able to function as an agonist in PBMCs (primary blood mononuclear cells) or not. A lower EC50 value is desirable in this assay since a compound with a lower EC50 value will be a better agonist in PBMCs. An acceptable test result is an EC50 value of less than 200 nM. Preferred assay results are EC50 values of less than 100 nM.

Caco-2 cells, grown in phenol red free, DMEM (Invitrogen, Carlsbad, Calif.) containing 10% charcoal-stripped FCS (Hyclone, Logan, Utah), were transfected with Fugene 6 reagent (Roche Diagnostics, Indianapolis, Ind.). Cells (5000/well) were plated 18 h before transfection in a 96 well plate. The Cells were transfected with Gal4-responsive reporter pFRLuc (150 ng, Stratagene, La Jolla Calif.) and the receptor expression vector pGal4-VDR-LBD (10 ng), along with Fugene 6 reagent (0.2 □l/well). The DNA-Fugene complex was formed by incubating the mixture for 30 min at room temperature. The cells were transfected in triplicate for 5 h, and treated with various concentrations of VDR ligands (form 0.01 nM to 10,000 nM concentration range) 18 h post-transfection. The luciferase activity was quantified using Steady-Glo reagent kit (Promega, Madison, Wis.) as per manufacturer's specifications.

(3) Materials and Method for The OCN Promoter Assay:

The activation of osteocalcin by VDR ligands was evaluated in a rat osteoblast-like cell line RG-15 (ROS 17/2.8) stably expressing rat osteocalcin promoter fused with luciferase reporter gene. The stable cell lines were established as reported before (Activation of Osteocalcin Transcription involves interaction of protein kinase A- and Protein kinase C-dependent pathways. Boguslawski, G., Hale, L. V., Yu, X.-P., Miles, R. R., Onyia, J. E., Santerre R. F., Chandrasekhar, S. J Biol. Chem. 275, 999-1006, 2000). Confluent RG-15 cells maintained in DMEM/F-12 medium (3:1) containing 5% FBS, 300 □g/ml G418 and at 37° C. under 5% CO₂/95% air atmosphere were trypsinized (0.25% trypsin) and plated into white opaque 96-well cell culture plates (25000 cells/well). After 24 hr, cells (in DMEM/F-12 medium+2% FBS) were treated with various concentrations of compounds, dissolved in DMSO. The final DMSO concentration remained at 0.01% (v/v). After 48 hr treatment, the medium was removed, cells were lysed with 50 □l of lysis buffer (From Luciferase reporter assay system, Roche Diagnostics, Indianapolis, Ind.) and assayed for luciferase activity using the Luciferase Reporter Gene Assay kit from Boehringer Mannheim as per manufacturer's specifications.

(4) Materials and Method for The Mouse Hypercalcemia Assay:

Weanling, virus-antibody-free, five to six weeks old female DBF mice (Harlan, Indianapolis, Ind.) are used for all the studies. Animals are allowed to acclimate to local vivarium conditions for 2 days. Mice are maintained on a 12 hr light/dark cycle at 22° C. with ad lib access to food (TD 5001 with 1.2% Ca and 0.9% P, Teklad, Madison, Wis.) and water. The animals then are divided into groups with 4-5 mice per group. Different doses of test compounds prepared in 10% Ethanol and 90% sesame oil are administered to mice orally via gavage for 6 days. 1α-25(OH)₂D₃ 0.5 μg/kg/d was also given to one group of mice as the positive control. Serum ionized calcium is evaluated at 6 hours after the last dosing under isoflurane anesthesia by Ciba-Corning Ca++/PH Analyzer, (Model 634, Chiron Diagnostics Corp., East Walpole, Mass.). Raw data of group differences is assessed by analysis of variance (ANOVA) using Fisher's protected least significant difference (PLSD) where the significance level was P<0.05.

(5) The Keratinocyte Proliferation Assay:

KERtr cells (Human skin keratinocyte transformed with a retrovirus vector, obtained from ATCC) were plated in 96-well flat-bottomed plates (3000 cells/well) in 100 □l keratinocyte serum free medium supplemented with bovine pituitary extract in the absence of EGF (Life Technologies, Rockville, Md.) and incubated at 37° C. for two days. The cells were treated with various concentrations of VDR ligands (ten-fold serial dilution from 10,000 nM to 0.1 nM in triplicate), dissolved in 100 □l keratinocyte serum free medium supplemented with bovine pituitary extract in the absence of EGF and incubated at 37° C. for 72 hr. BrdU (5-bromo-2′-deoxyuridine) incorporation was analyzed as a measure of DNA replication (Cell proliferation ELISA kit, Roche Diagnostics, Indianapolis, Ind.) and absorbance was measured at 405 nm. Potency values (IC₅₀) values were determined as the concentration (nM) of compound that elicited a half-maximal response.
